For class providers sfcb is acting like Pegasus. It translates the 
CIM_RASD call into a separate provider request for each subclass.

Besides that tiny compilation issue I had no trouble with the provider - 
neither with sfcb nor with Pegasus. And by reviewing the code I have no 
idea, where this behavior could come from. For me everything looks fine.

What is really strange is, that for nearly the same call two different 
functions are returning errors:
- for the first one (ein) the provider is returning the error
- for the second one (ei) the CIMOM is returning the error ... and that 
error looks like Pegasus is having trouble with calling the same 
provider for different subclasses
Please can you reinstall, restart Pegasus and try again ? What happens ?
